A not-for-revenue organization, IEEE is the earth's largest complex Specialist Corporation committed to advancing know-how for the benefit of humanity.

Consequently There's minimal freedom for optimizing the dispersion payment influence. Sub-two hundred fs pulses is usually anticipated which has a broader bandwidth seed input. Because of the twin-crystal configuration, the laser cavity provides a near diffraction restricted laser beam with M

-switched manner. The bandwidth while in the orthogonal orientation was Obviously Significantly broader. The calculated Fourier remodel minimal pulse duration was as brief as sub-160 fs. Beneath the configuration exactly where The 2 crystals ended up positioned in a similar orientation, With all the seed input, the amplified pulse bandwidth was only 3 nm with a hundred and eighty μJ Vitality when it broke the dichroic mirrors.

The calculated Slash-off wavelengths in the brief-wavelength facet are according to the overall development of blue-shifted spectral broadening over the bandgap of nonlinear product. Every one of the nonlinear resources manufactured sensible pink-shifted spectral broadenings underneath ailments of optimal pump pulse energies, with the largest pink-change exceeding 2000 nm measured in GGG crystal. Our effects unveiled that GGG and BGO (which also had the bottom supercontinuum technology threshold) offer you resilient, optical harm-totally free functionality in a laser repetition level of two hundred kHz, suggesting that these supplies are very good alternate options to YAG and KGW for very low threshold, superior average electric power supercontinuum generation within the in the vicinity of- and short-wave infrared spectral ranges. We also demonstrated that scintillating Qualities of bulk elements can be conveniently examined inside the filamentation regime, by using multiphoton excitation applying near-infrared femtosecond laser pulses.

The opposite was put with its Np -axis parallel While using the s-polarized course. A comparison was produced concerning a configuration Together with the crystals placed in a similar orientation (

Thermal outcomes are appreciably more compact in KGW. This combined with the higher harm threshold make the crystal a wonderful candidate for power scaling. Comparing Ba(NO3)2 and KGW for Raman application Ba(NO3)2 are more practical in the event of ns pulses and KGW �?in case of ps pulses.

The threshold Power for SC era (hbox E _ textrm th ) was described since the pump pulse Power, wherever the blue-shifted spectral broadening promptly settles to a certain Lower-off wavelength That is still almost continuous Despite even further raise of your pump pulse energy. The optimum Vitality (hbox E _textrm choose ), was outlined given that the pump pulse Power, which generates the biggest pink-shifted spectral broadening ahead of the onset of periodic modulation from the SC spectrum as a consequence of filament refocusing.

Both energies are marked because of the dashed traces as well as their values are labeled from the plots. The similar click here functions have been also noticed in KGW and YAG crystals, whose spectral broadening dynamics are shown for your comparison in Fig. four.
